     Zipped into a bag it looks like a large umbrella. Unfolded it goes along the street like any other bicycle.
     It's the "A-bike" the brainchild (脑力劳动的产物) of British inventor Sir Cive Sinclair who made history
in the 1970s hy devel oping the world's first pocket calculator. He described his new invention as "the world's
smallest lightest foldable bicycle".
     "My original thought was that if you could have a bicycle that was dramatically lighter and more firm than
the ones that exist today it would change the way in which bicycles are used " said Sinclair.
     The mini-bike showed in Singapore last week and set to go on sale worldwide in 2005 at a price of nearly
US $300 is built for riders as heavy as 112 kilograms and is height-adjustable (可调整高度的). It takes about
20 seconds to fold or unfold.
     Its wheels are a quarter the size of those on a regular bicycle but Sinclair promises a smooth ride for most
cyclists. "You require no extra energy to ride the A-bike and it can go up to 15 miles per hour (24 kilometers
per hour) " he said. Constructed mainly of plastic the 5.5-kilogram bicycle folds into a package of less than
0.03 cubic meters (立方米).
     Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he
hoped the bicycle would attract common citizens officials campers or anyone needing transport for a short
trip and he said the next step for the A-bike was to add an electric motor in a few years.
